REFUSE BUR-NEE.

' Application filed January 29, 1926.

N My present invention has to do with the destruction of refuse; and it contemplates the provision of a refuse burner which while simple and inexpensive in construction and '5 adapted to be efficiently operated with but little attention is possessed of the practical advantages hereinafter ascribed to it in general and also ascribed to certain of its features explicitly referred to.

l/Vith the foregoing in mind the invention in all of its details will be fully understood from the following description and claims when the .same are read in connection with the drawings accompanying and forming part of this specification, inwhich Figure 1 is a view, partly in side elevation and partly in vertical section, illustrating the refuse burner constituting the best practical embodiment of my invention of which I am cognizant.

Figure 2 is a front end elevation of the burner.

Figure 3 is a vertical cross section taken in the planeindicated by the line 3-3 of Figure 1. 1

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel refuse burner comprises a combustion chamber 1 which may be and preferably is formed of concrete lined with fire brick but which may be specifically constructed in any other manner consonant with the purpose of my invenof appropriate character is provided at the bottom of the combustion chamber 1, and below the grate is an ash pit 3, the door to which is designated by 4, Figures 1 and 2. At the back of the combustion chamber 1 is a transverse wall 5 with an inclined face 6 which extends upwardly to an opening 7 intermediate of the rear end of the upper portion of the combustion chamber 1 and a cold air compartment designated by 8. The cold air compartment 8 is also formed of appropriate material or materials and is in direct communication with a suitably constructed uptake 9 which is preferably, though not necessarily, equipped at its upper with a spark arrester 10 of suitable reticulated material. I would also have it understood at this point that when deemed xpedient a vertically swingable striker 11 maybe located in the spark arrester 10, the

said striker 11 being pivoted at 12 and having an arm 13 exterior of the arr-ester 10 and to which is connected a pendent operating; rod 14 through the medium of which the striker 11 may be manipulated for the displacement by concussion of the striker against the screen of soot accumulations and the like.

The cold air compartment 8 is provided in its side walls with openings 15 for the entry at all times of atmospheric air.

At 16 is a chute of inclined character through which refuse to be destroyed is conveyed to a point within the combustion chamber 1 at the top thereof.

The side walls of the combustion chamber 1 are hollow as designated by 17. The upper portions of these air spaces 17 are connected at all times with the atmosphere through the medium of openings 18, Figures 1 and 8, and the lower ends of the said spaces 17 are in full and free communication with the ash pit 3. By virtue of this provision'it will be manifest that ample air for the support of combustion will be con ducted to the ash pit 3, and at the same time the side walls of the combustion chamber 1 will be adequately cooled.

As best shown in Figure 2, the front wall of the combustion chamber 1 is provided with a manhole 19, and is also provided with a reticulated frame 20 above and at opposite sides of the said manhole. Manifestly this provision assures the supply of an ample quantity of atmospheric air at all times in the front portion of the combustion chamber 1.

An important feature of my invention resides in the fact that myburner is free of doors, gates, shutters or analogous devices for regulating currents of air, but on the other hand the regulation of the air supply is controlled by the requirements in the combustion chamber 1. This will be better understood when it is stated that the operation of my novel burner is based upon a plurality of automatic drafts that center in and control the mass in the combustion chamber 1 so that as air is required air is automatically supplied by the conditions arising from the volume of the burning mass, and in this way a cushion of air is constantly formed automatically as required, the same being supplied throu the medium of the air induction means dist closed. Nothing is permitted to escape from the combustion chamber save hot air and gas which striking the rear of the combustion chamber 1 and being deflected to or caused to enter the automatically cooled compartment 8 and passing from said compartment 8 through the uptake 9 is cooled by the compartment 8 so that the uptake or stack 9 is never unduly hot. Again it will be understood that the cushion created in the manner described operates to exert downward pressure on the burning mass so as to assure combustion of the mass from the base and interior thereof, and lessening the liability of cinders being formed and also lessening the liability of a considerable amount of ashes being left.

It follows from the foregoing that but little heat is radiated from my novel burner including the uptake or stack 9, as is desirable.

Notwithstanding the practical advantages of my novel refuse burner as described, it will be noted that the burner is simple and inexpensive in construction, and, in addition to the before mentioned advantages the burner is materially advantageous inasmuch as it requires during operation practically no attention other than the feed of refuse to the combustion chamber 1.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the structure and ar rangement precisely as disclosed, my invention being defined by my appended claims within the scope of which changes in structure and in arrangement may be made witlr out departure from my invention.

Having described my invention what I claim and desire to secure by Letters-Patent, 1s
